Falling prevention structure for socket of power tool

Abstract

An object of the present invention is to prevent a socket from falling off by means of a simple and compact configuration without impairing comfort and ease of use, regardless of model. In an impact driver, a connecting ring in which a protrusion including a through hole protrudes from an outer periphery thereof is clamped detachably to an outer periphery of a shaft support portion of a hammer case. By a carabiner passing through a ring of a socket and the through hole in the connecting ring and engaging the carabiner, a socket portion can be prevented from falling off when a bit portion is broken.
